Black level calibration is controlled by:
• Frame Dark Average: R0x42
• Dark Average Thresholds: R0x46
• Black Level Calibration Control: R0x47
• Black Level Calibration Value: R0x48
• Black Level Calibration Value Step Size: R0x4C
The MT9V034 has automatic black level calibration on-chip, and if enabled, its result
may be used in the offset correction shown in Figure 26.
